Enphase IQ9 Microinverters

The greenest inverter on the roof

The hardest-working part of your solar system is the one you’ll never see.

Your panels catch the sunlight — but every solar system needs a translator: the part that turns raw sunlight into the AC power your home can actually use. In most systems, a slice of that clean energy is quietly lost in translation, shed as heat before it ever reaches a light switch. The greener the conversion, the more of your own sunshine you keep.

The Enphase IQ9 Microinverter is built to lose as little as possible. It’s the first Enphase residential microinverter powered by gallium nitride (GaN) — a semiconductor that switches faster and runs cooler than the silicon inside conventional inverters, converting more of what your panels produce into usable power. Less waste heat, more clean energy, from the very same sunlight falling on the very same roof.

Because every IQ9 sits beneath its own panel, each module works independently. A leaf, a chimney’s shadow, a smear of pollen on one panel no longer drags down the rest — so across a real, imperfect roof, you harvest more of the sun that’s actually available. And by converting to AC right at the panel, there are no long, high-voltage DC runs across your roof: a safer, all-AC design with rapid shutdown built in.

Here’s the part most inverter marketing skips. Like a battery, an inverter’s real environmental cost is paid up front — the day it’s made — so the greenest inverter isn’t the one with the flashiest peak number, it’s the one that harvests the most clean energy before it ever needs replacing. That’s lifetime value, counted in kilowatt-hours and years. GaN runs cooler, and cooler electronics last longer, so the IQ9 is engineered to hold peak performance season after season and is backed by a 25-year warranty — among the longest in the industry. More clean energy captured across its life, less embodied carbon behind every kilowatt-hour, and less waste at the end of the road. And because it’s backward-compatible with existing IQ7 and IQ8 systems and works with IQ Batteries, you build on what you already own rather than tearing it out and starting again. The greenest inverter is the one you never have to replace.

• A 25-year warranty — among the longest in the industry, engineered to keep harvesting at peak for decades, not years.
• GaN efficiency — gallium nitride converts more of your panels’ output into usable power and wastes less as heat than conventional silicon inverters.
• Ready for the latest panels — pairs with today’s premium high-wattage modules to pull more energy from every square metre of roof.
• Peak power in every panel — per-panel conversion keeps the rest of your system producing when one panel is shaded, soiled, or offline.
• Built for a harsh climate — corrosion-resistant and rated from –40°C to +65°C, holding performance through heat, cold, and coastal air.
• Low-voltage, high safety — an all-AC rooftop architecture with rapid shutdown, avoiding the hazards of high-voltage DC.
• Builds on what you have — backward-compatible with IQ7 and IQ8 systems and IQ Batteries, so you expand rather than replace.
